Looks very promising.

  Pin #1 connected to #13 with thick connection (power)

  All pins in the lower row except for #12 seems to be connected to the
surrounding ground plane.

And not sure if there is anything else besides pinheader missing.

17J2(?) looks like it may be some kind of power connector judging from
the traces.

But according to the markings there is an unpopulated USB connector next
to it, and the data trails from that one runs straight into 17J2 which
is a bit confusing if 17J2 is power related.

No idea.

There is only 3 USB controllers in A10. One OTG and two host.
